           Summary: Thumbnails flicker
           Product: digikam
           Version: 2.0.0
          Platform: Gentoo Packages
        OS/Version: Linux
            Status: UNCONFIRMED
          Severity: normal
          Priority: NOR
         Component: general
        AssignedTo: digikam-devel at kde.org
        ReportedBy: bugs at seeitmyway.org


Version:           2.0.0 (using KDE 4.7.0) 
OS:                Linux

Sometimes my thumbnails start to flicker madly. Only way to stop them doing
that is to restart digiKam. One example of something that can trigger thumbnail
flicker is renaming a dir with many images in it. During renaming, they start
to flicker.

I can provide a screencast if this is not a known issue.

I think this flickering (the triggering of a directory monitoring procedure?)
might be what makes digiKam so slow at renaming many files. Instead of just
renaming them all (~700 files) in a second (as a bash script would take: for f
in *.jpg; do mv "$f" "renamed_$f"; done), and then updating the thumbnails,
it's taken already a few minutes and it's at 58% as I write.

Reproducible: Always

Steps to Reproduce:
Rename many files.


Expected Results:  
No flicker of thumbnails. Renaming should be very fast.
